I strongly disagree. I've never heard anything like that from anybody,
except perhaps from someone I once knew who spoke broken English,
In my opinion, (1) is terrible. It would be far from the top of my
preferred order.
>(4) seems a bit illogical _before_ the speaker actually puts it in his/her mouth.
I think it's fine, not at all illogical.
Also fine is "This is the first time I ate sushi."

That's also OK.
An aside: I've been eating sushi since about 1954. I started in a
Japanese restaurant in NYC. I think that in those days it was one of
the only three Japanese restaurants in the USA; they were all in NYC.
It's still one of my favorite foods, although I only eat nigiri and
gunkanmaki, almost never rolls. If it weren't so expensive, I'd eat
sushi more often--maybe twice a week.
